Function

VDRA_DANRE Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Plays a central role in calcium homeostasis.^[1]

Publication Abstract from PubMed

The hypercalcemic effects of the hormone 1alpha,25-dihydroxyvitamin D(3) (calcitriol) and most of known vitamin D metabolites and analogs call for the development of non secosteroidal vitamin D receptor (VDR) ligands as new selective and noncalcemic agonists for treatment of hyperproliferative diseases. We report on the in silico design and stereoselective synthesis of six lithocholic acid derivatives as well as on the calcemic activity of a potent LCA derivative and its crystallographic structure in complex with zVDR LBD. The low calcemic activity of this compound in comparison with the native hormone makes it of potential therapeutic value. Structure-function relationships provide the basis for the development of even more potent and selective lithocholic acid-based VDR ligands.
